In this embodiment, a program backup processing method operating in the mobile terminal or the network architecture is provided, and fig. 4 is a flowchart of the program backup processing method according to the embodiment of the present invention, as shown in fig. 4, the flowchart includes the following steps:
step S402, acquiring the lengths of program areas of a plurality of sub-areas of a main program area of a memory, wherein the main program area comprises the plurality of sub-areas, and the plurality of sub-areas comprise the program areas and reserved areas;
for an embedded system, data files required generally can be divided into running program files and resource files, and the embodiment of the present invention is mainly directed to backup of the running program files, and certainly, the present invention is also applicable to the resource files.
Further, for each partition of the plurality of partitions, performing the following operations, wherein each partition is referred to as a current partition when performing the following operations: and determining the length between the position of the first program with the non-preset identification and the starting positions of the plurality of partitions from the last forward search of the current partition as the length of the program area of the current partition.
Step S404, splicing the program areas of the plurality of partitions according to the lengths of the program areas of the plurality of partitions, and backing up the spliced program areas into a backup partition of a standby program area of the memory, wherein the space of the main program area is larger than that of the standby program area;
specifically, only the program area of the main program area containing the program files is backed up and spliced in one backup partition of the backup program area, so that the space occupied by the backup program files is effectively saved.
Step S406, a target reserved area is set at the last of the backup partitions, wherein the space of the target reserved area is smaller than the sum of the spaces of the reserved areas of the plurality of partitions.
Specifically, a reserved area is uniformly arranged behind the program files backed up in the backup partition, and the space occupied by the reserved area is far smaller than the sum of the reserved areas of the program areas in the main program area, so that the space occupied by the backup is greatly reduced.
Through the steps S402 to S406, the problem that the system started after failure is the minimum system with the cut functions and can be used only after secondary upgrade in the related art can be solved, a compact full backup mode is used in the memory, the space used for backup can be greatly reduced, and the effect of full backup can be achieved, and the system can be directly used without secondary upgrade.
According to the embodiment of the invention, the program areas of the plurality of partitions are spliced according to the lengths of the program areas of the plurality of partitions, the spliced program areas are backed up in one backup partition of the backup program area of the memory, a target area is reserved at the initial position of the backup partition, and the number of the backed-up partitions, the sequence of the backup partitions and the lengths of the program areas of the plurality of partitions are indicated by the target area, so that the backed-up content can be restored to the main program area subsequently.
Optionally, after splicing the program areas of the multiple partitions according to the lengths of the program areas of the multiple partitions and then backing up the spliced program areas of the multiple partitions into one backup partition of a backup program area of the memory, if it is detected that the program of the main program area is damaged, the programs of the multiple partitions of the main program area are restored through the backup partition of the backup program area. Further, erasing the plurality of partitions in the main program area; and restoring the programs in the backup partitions to a plurality of partitions of the main program area according to the sequence of the backup partitions.
The memory can be a flash, particularly a Nand flash, and devices in related technologies have requirements on backup functions, and backup mainly ensures that the devices can normally operate after being upgraded or abnormal due to other reasons. The embodiment of the invention is based on a compact program backup mode, analyzes the program storage mode of full backup 1:1 in Nand flash, and can find most practical use cases as follows, fig. 5 is a schematic diagram of the program full backup storage mode according to the related art, as shown in fig. 5, each partition has a plurality of unused areas, shadow parts belong to the unused areas in the partition, and the areas are reserved, on one hand, the Nand flash has bad blocks, generally 5% of the bad blocks are allowed, the positions of the bad blocks are random, but the partition is performed according to a fixed format, so that a space of the bad blocks must be reserved for each partition; another aspect is to reserve space for subsequent extensions of the program.
According to the backup mode of 1:1, a lot of space is actually wasted, fig. 6 is a schematic diagram of a storage mode of a compact backup according to an embodiment of the present invention, as shown in fig. 6, these wasted reserved areas are saved back, a compact mode is adopted for backup, only areas with programs are backed up, the whole backup program is compacted to form a backup partition, after being merged into a partition, only a bad block area of a large partition needs to be reserved, and meanwhile, an area reserved for subsequent expansion can also be saved (generally, the reserved area of each partition is not used last, only a part needs to be reserved properly). The compact backup approach also requires an extra header information to record the actual size of each partition.
If only the actual area of the program in each partition is backed up, the actual area size of each partition needs to be acquired first. The Nand flash has a characteristic that each byte of data of an unused block after erasure is 0xff, and there is an ingenious way to obtain the size of each partition: from the back to the front, starting with the last 0xff, the actual size of the program can be calculated if data other than 0xff is found, indicating that the end of the actual program area is found. Certainly, there is an extreme case that the last of the program is composed of many all-0 xff byte data, and it does not matter, this part of data may not need to be backed up, the whole partition is erased before the program is restored, the erased data is 0xff, and then restoration is performed, the data which is not modified after the restoration is completed is all-0 xff, which is equivalent to that this part of all-0 xff data which is not backed up is also restored.
By the embodiment of the invention, a compact full backup mode is used in the Nand flash, the space used by backup can be greatly reduced, and the effect of full backup is achieved. Compared with a full backup mode, the compact backup only backs up the part actually provided with the program, the quantity of the backed-up program is reduced, the calculation method is simpler, the calculation quantity is small, the backup speed is higher than the full backup speed, and the backup time is saved.
